January 19 We collected Sooties and autopsied
in The morning. Total of 65 dead or badly
injured, plus 2 Common Noddies. Autopsied 13,
none with blood patches, 3 molting (2 at least) each.
One tail feather each.
Found one Blue-faced Booby on guywire base #7.
With the exception of 2 imm-5A at 1900, no
Browns even sitting on the hill in morning
or evening.
Afternoon spent on task work. Checked the other
end and collected Belizees 1900. Banded from
2030-0030, total of 400+ first hundred checked
for blood patches (0) and molt (2 at 1 outer reticul).
No Graybacks nesting yet. They are on the
islet and pier and a few were on the rocks
above The pier after dark.
Returned me Hawaiian Noddy while banding.
Total of 7 Blue-faced on #7 1900.
About 150 adult frigate in nesting colony,
many immatures sitting around periphery.
Sooties begin to mass offshore about 1600. They
form two swirls, one off north side, other off
south. They do not come in over island until
about 1900, funneling in from west but
not flying much over the causeway except for
streaming across it earlier. First birds
alighting about 1915, low in area D about 1/3 the
way from the road. There seem to be Two
Groups of birds, some swirling fairly close +
streaming back & forth over island; others are

January 19 far out and in greater numbers,
apparently do not come in to land as early as
the former group. Perhaps latter are the first
arrivals, which now form a cohesive unit
after perhaps having built up to a number
which could trigger a new phase of behavior.
There was no moon while we were out and the
birds seemed to be holding rather well. Also,
they are down over a large area, including area
13 and area D between roads shore.
January 20 Same routine as yesterday. Only 3-4
Blue-faced present on #6 guywire base in A.M. Banding
2030-0015, Total 500 Sooties. We worked the
east side of the Xmitter building, found the birds
much more edgy than on south; finished on South.
Saw two Sooties standing on dead ones, either
outbacking or attempting copulation.
January 21 Hourly counts on Sooties & Frigates
today. Summary: Redfots decrease sharply right
around sunrise, remain fairly constant thereafter
until evening influx between 5-7, though much
shifting around was noticed from about 4 P.M.,
Browns concentrated on hill until about 8, then
drop off until 1200, then remain steady until
1500, mainly on guywire bases & pilings; increase
again between 4-5 P.M., coming back to the
hill until 6, then moving back out to platforms
& bases, almost exclusively immatures in colony
site during the day. Some bill-fencing noted in
9 P.M.
